Question

我正在使用 UIImagePickerController 从设备获取图像。我已经实现了以下步骤:

1. 已获得许可: 隐私 - 照片库使用说明 - info.plist

2. 创建并显示 UIImagePickerController 的实例。代表被分配给自己。相机或库选项由 UIAlertController 提供。

   -(void) openGallery {
       UIImagePickerController *picker = [[UIImagePickerController alloc] init];
       picker.delegate = self;
       picker.allowsEditing = YES;
   
       UIAlertController *actionSheet = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
       }]];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
           // take photo button tapped.
           picker.sourceType = UIImagePickerControllerSourceTypeCamera;
           [self presentViewController:picker animated:YES completion:NULL];
       }]];
   
       [actionSheet addAction:[UIAlertAction actionWithTitle:@"Photo Library" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
           // PhotoLibrary
           picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
           [self presentViewController:picker animated:YES completion:NULL];
       }]];
   
       [self presentViewController:actionSheet animated:YES completion:nil];
   }
   

3. 在代理上，图像已经到达，但是当我尝试将其转换为 base64 后上传到服务器时，AFNetworking 抛出错误:

   Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled} with Objective C Xcode 9.3 iOS 11

   #pragma mark- UIImagePicker Delegate
   
   - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
       UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
   
       [picker dismissViewControllerAnimated:YES completion:NULL];
   
       [self.view setUserInteractionEnabled:NO];
       [self uploadThemeServiceCall: chosenImage];
   }
   

我尝试创建 OS_ACTIVITY_MODE 以在环境变量中禁用，但没有成功。我尝试了其他可用的解决方案，但仍然没有用。它工作正常，但现在不行了。

Answer 1

A:) 确保对象 selectedImage 不为零。 B:) 使用 NSData *imageData = UIImageJPEGRepresentation(imageObject , 1) 将 chosenImage 转换为 NSData 。使用此 imageData 作为您的 NSUrlRequest 正文。

另请在此处显示函数 uploadThemeServiceCall 的代码。
